CALIBRATION MEASUREMENTS USING THE ORNL FISSILE MASS FLOW MONITOR

This paper presents a demonstration of fissile-mass-flow measurements using the Oak Ridge National Laboratory (ORNL) Fissile Mass Flow Monitor in the Paducah Gaseous Diffusion Plant (PGDP). This Flow Monitor is part of a Blend Down Monitoring System (BDMS) that will be installed in at least two Russian Federation (R.F.) blending facilities. The key objectives of the demonstration of the ORNL Flow Monitor are two: (a) demonstrate that the ORNL Flow Monitor equipment is capable of reliably monitoring the mass flow rate of 235UF6 gas, and (b) provide a demonstration of ORNL Flow Monitor system in operation with UF6 flow for a visiting R.F. delegation. These two objectives have been met by the PGDP demonstration, as presented in this paper.
